run the command in X11 and then switch to console to await the crash
that way you'll see if there is a messsage (or serial console I guess).
A panic when X is running will not sto pbecause it assumes you can't look at it.
so it just reboots.  (I haven't seen the code that does this but I've
observed the behaviour).

could it be achieved by anything tha scrolls that amount of data?
(e.g. catting a huge file?) if so it may just be bad thermal control
as teh cpu is doing all that renderring.
